Question

resuelve la siguiente ecuación
1. x - 19 = -15
2. 8 - x = 17
3. x + 3 = -5
4. 4x = -24
5. -7x = 42
6. 2x - 19 = -15
7. 3x - 9 = -21​

Answer 1

1. x = -15 + 1

x = 4

2. 8 - 17 = x

-9 = x

3. x = - 5 - 3

x = - 8

4. 4x = -24

x = - 24/4

;; x = - 6

5. 42 = 7x

42/7 = x

6 = x

6. 2x = - 15 +19

x = 4/2 = 2

7. 3x = -21 + 9

x = -12/3 = - 4

Answer 2

Respuesta

1. x - 19 = -15

x = - 15 + 19

x = 4

2. 8 - x = 17

x =  17 - 8

x = 9

3. x + 3 = -5

x = - 5 - 3

x = - 8

4. 4x = -24

x = -24 / 4

x = -6

5. -7x = 42

x = 42 / -7

x = -6

6. 2x - 19 = -15

2x = -15 + 19

2x = 4

x = 4 / 2

x= 2

7. 3x - 9 = -21

3x = -21 + 9

3x = -12

x = -12 / 3

x = -4
